Checking BPTP Astaire Garden Plots: My concerns

Is anyone else worried about BPTP's customer support for Astaire Garden Plots after booking? I'm looking at a plot there on Golf Course Extension, and honestly, bank approvals seem a bit slow compared to other builders. My parents keep saying to check the builder's financial health thoroughly before committing to a first property. Don't want to get stuck if there are issues later or face project stalling. Should I be concerned about getting proper updates or even reaching them? Any experiences with their post-booking service?
